Over 90% of bottled water contains microplastics; WHO issues alarm

A new analysis by a group of scientists has found that more than 90% of the world’s most popular bottled water brands contained tiny pieces of plastic. The shocking revelation has prompted the World Health Organisation (WHO) to announce a review into the potential risks of plastic in drinking water.

Analysis of 259 bottles from 19 locations in nine countries including India across 11 different brands found an average of 325 plastic particles for every litre of water being sold. Concentrations were as high as 10,000 plastic pieces for every litre of water. Of the 259 bottles tested, only 17 were free of plastics, according to the study.

Scientists based at the State University of New York in Fredonia were commissioned by journalism project Orb Media to analyse the bottled water. The scientists wrote they had “found roughly twice as many plastic particles within bottled water” compared with their previous study of tap water.

According to the new study, the most common type of plastic fragment found was polypropylene – the same type of plastic used to make bottle caps. The bottles analysed were bought in the US, China, Brazil, India, Indonesia, Mexico, Lebanon, Kenya and Thailand.

Scientists used Nile red dye to fluoresce particles in the water – the dye tends to stick to the surface of plastics but not most natural materials.

New Delhi, Mar 27: The Centre has restricted sale and distribution of "hydroxychloroquine" declaring it as an essential drug to treat the COVID-19 patients and meet the requirements of emergency arising due to the pandemic.

The Ministry of Health and Family Welfare on Thursday made the announcement making it clear that the order "shall come into force on the date of its publication in the official Gazette".

In the order, the government declared that the Central government is "satisfied that the drug hydroxychloroquine is essential to meet the requirements of emergency arising due to pandemic COVID-19 and in the public interest, it is necessary and expedient to regulate and restrict the sale and distribution of the drug 'hydroxychloroquine' and preparation based thereon for preventing their misuse".

"Now, therefore, in exercise of the powers conferred by Section 26B of the Drugs and Cosmetics Act, 1940 (23 of 1940), the Central government hereby directs that sale by retail of any preparation containing the drug Hydroxychloroquine shall be in accordance with the conditions for sale of drugs specified in Schedule H1 to the Drugs and Cosmetics Rules, 1945."

The order came at a time when the novel coronavirus claimed 16 lives and infected over 600 people across India.

The announcement regarding ban of sale and distribution of the drug was made by the government earlier but it issued an official Gazette notification on Thursday signalling that hydroxychloroquine -- an anti-Malaria drug -- will work as a medicine for treating coronavirus infected patients as well.

Recently, the national task force for COVID-19 constituted by Indian Council for Medical Research (ICMR) has recommended hydroxy-chloroquine as a preventive medication.

High-protein diets may help people lose weight and build muscle, but there is a downside to it --a greater heart attack risk. Researchers now report that high-protein diets boost artery-clogging plaque.

The research in mice showed that high-protein diets spur unstable plaque -- the kind most prone to rupturing and causing blocked arteries.

More plaque buildup in the arteries, particularly if it's unstable, increases the risk of heart attack.

"There are clear weight-loss benefits to high-protein diets, which has boosted their popularity in recent years," said senior author Babak Razani, associate professor at Washington University School of Medicine in St. Louis, Missouri.

"But animal studies and some large epidemiological studies in people have linked high dietary protein to cardiovascular problems. We decided to take a look at whether there is truly a causal link between high dietary protein and poorer cardiovascular health," Razani added.

The researchers studied mice who were fed a high-fat diet to deliberately induce atherosclerosis, or plaque buildup in the arteries.

Some of the mice received a high-fat diet that was also high in protein. And others were fed a high-fat, low-protein diet for comparison.

The mice on the high-fat, high-protein diet developed worse atherosclerosis -- about 30 per cent more plaque in the arteries -- than mice on the high-fat, normal-protein diet, despite the fact that the mice eating more protein did not gain weight, unlike the mice on the high-fat, normal-protein diet.

"A couple of a scoop of protein powder in a milkshake or smoothie adds something like 40 grams of protein -- almost equivalent to the daily recommended intake," Razani said.

"To see if protein has an effect on cardiovascular health, we tripled the amount of protein that the mice receive in the high-fat, high-protein diet -- keeping the fat constant. Protein went from 15 per cent to 46 per cent of calories for these mice".

Plaque contains a mix of fat, cholesterol, calcium deposits and dead cells. Past work by Razani's team and other groups has shown that immune cells called macrophages work to clean up plaque in the arteries.

But the environment inside plaque can overwhelm these cells, and when such cells die, they make the problem worse, contributing to plaque buildup and increasing plaque complexity.

"In mice on the high-protein diet, their plaques were a macrophage graveyard," Razani informed.

To understand how high dietary protein might increase plaque complexity, Razani and his colleagues also studied the path protein takes after it has been digested -- broken down into its original building blocks, called amino acids.

"This study is not the first to show a telltale increase in plaque with high-protein diets, but it offers a deeper understanding of the impact of high protein with the detailed analysis of the plaques," said Razani.

"This work not only defines the critical processes underlying the cardiovascular risks of dietary protein but also lays the groundwork for targeting these pathways in treating heart disease," he added.

Bengaluru, Mar 13: This year, schoolchildren will have a longer summer vacation starting early, thanks to the new coronavirus onslaught. Primary and Secondary Education Minister Suresh Kumar on Thursday announced that schools in Bengaluru Urban and Rural districts will be closed for vacation from Friday.

Classes from LKG to sixth standard will closed for vacations till the schools reopen in June, while students of classes 7-9 will have ‘study holidays’ until their examinations commence (as scheduled by their respective schools). Their summer vacations will begin with the completion of their examinations.

Class 10 students will have their examinations according to the dates scheduled earlier.

“Let us not treat this as a panic reaction or something to cause a scare. This measure is taken as a precaution. A lot of parents were worried about their children. We have already announced the closure of schools from nursery to sixth standards. Now, we are declaring official holidays upto sixth standard. Students of standards 1-6 will all be promoted based on their formative assessment,” said Kumar adding, “no student will be detained in those classes.”

With respect to seventh, eighth and ninth standards, the schools will be closed for study holidays and students will have to return to write their examinations.“We will not interfere in the examination schedules of CBSE and ICSC schools. However, state syllabus schools have to finish their examinations before March 23”, Public Instruction Commissioner KG Jagadeesh said.Just a couple of papers of the PU examinations are left after which their holidays will begin.

Exam timetable not changed

Miscreants are spreading rumours that SSLC examination dates are changed because of the new coronavirus outbreak. However, Karnataka Secondary Education Examination Board director V Sumangala categorically said the examinations will be held from March 27  to April 9 as scheduled earlier.
